Have a look at

Procedure, subroutine or function?, Object-oriented programming

An object is actually a discrete bundle of functions and procedures, all relating to a particular real-world concept such as a bank account holder or hockey player in a computer game. Other pieces of software can access the object only by calling its functions and procedures that have been allowed to be called by outsiders.

Basically, you use a function/procedure/method to encapsulate a specific section of code that does a specific job, or for reusibility.

Classes are used to encapsulate/represent an object with possibly its own data, and specific function/procedure/method that makes sense to use with this object.

In some languages classes can be made static, with static function/procedure/method which can then be used as helper function/procedure/method
